Incredible craftsmanship and mechanics, i have shot 2000 rounds through my glock 21 and it shows very little wear, can't say same about my XDm .40 and PX4 9mm, bought them all about the same time and the glock and their wear factor on the factory blueing inside of the slide and on the barrel is 2 to 1 that of my glock, also easiest of any of my guns to clean. I don't understand the glock haters, never heard of a glock lover that is a 1911 hater.
